Keto Vanilla Strawberry Swirl Layer Cake With Buttercream Frosting

keto cake recipeHello!

How are we feeling, friends? As we enter week 2 of self-quarantining, I decided to pick up one of my long-lost favorite hobbies: baking!

When I was in high school and college I would bake almost weekly. Cookies, cakes, brownies, buckeyes, anything I could get my hands on. I even had a cooking blog in college where I’d share my favorite recipes! 

When I got diagnosed with PCOS (read more on that here), I changed my dietary habits and subsequently stopped baking. Sugar is one of the worst foods for women with PCOS as it aggravates hormones, and can lead to insulin resistance and a slew of other nasty side effects. And in my mind, baking and sugar were synonymous…until recently.

About a year ago I tried a keto lifestyle for about 3 months before deciding to switch to low-carb (which I follow at least 5/7 days a week when I’m not on vacation). Eating this way makes me feel so good and makes managing my PCOS symptoms way easier. But, I definitely missed my sweets! I discovered Lily’s Sweets, Keto Bites, Quest Cookies, Enlightened Ice Cream, and sugar & flour alternatives that were not only delicious but healthy! So I was back in business.strawberry keto cake

Fast forward to this Valentine’s Day. I wanted to make something really special for Doug (he loves cake), but I also wanted it to be healthy and make us feel good. Enter this keto vanilla strawberry swirl cake with buttercream frosting. It was AMAZING and only has 5.5 g net carbs per slice!

I found this vanilla cake mix by Swerve a few months ago and have been using it as the base for all types of yummy treats since. I used it to make the strawberry swirl cake the first time around, but I didn’t write down the recipe because I made the majority up as I went. I am definitely not a recipe follower! lol

So this weekend with all of the extra time on my hands, I decided to recreate the keto vanilla strawberry swirl cake and write down the recipe. This cake is gluten-free, keto, sugar-free, low-carb, diabetic-friendly and just all-around delicious. I will give some vegan alternatives as well, but just note that I have NOT tried this recipe with the vegan ingredients. 

I hope you love this cake as much as we did!

Tools needed: Large mixing bowl, whisk, 2 round cake pans, butter knife or toothpick, measuring cup

  • Set your oven to 350 degrees Fahrenheit (or whatever your boxed cake mix says).

  • Add your eggs, water, oil and vanilla extract to the dry mix. Stir with a whisk until everything is incorporated.

  • Pour half of the wet cake mix into both of your pans.
